LIGHTING-FIXTURE.

Specification of Letters Patent.

Applcation filed January 9, 1914.

To all whom t may concern.'

Be it known that I, CHARLES D. SPEELMAN, aI citizen of the UnitedStates, residing at St. Joseph, in the county or' Buchanan and State ofMissouri, have invented certain new and useful Improvements inLighting-Fixtures; and l dodcclare the following to be a full, clear,and eXact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters andfigures of reference marked thereon, which form part of thisspecification.

My .invention relates to lighting fixtures, and more particularly to aconnection for the ceiling and hanger pipes in a gas lighting system;vhe principal object of the invention being to provide means fororiginally straightening the down sections of the ceiling pipe andretaining same in perpendicular alinement.

It is also an object of theinvention to provide a connection of thischaracter for use with combination gas and electric light fixtures, andwhich may not only serve to straighten and stiiien the down pipes butmay also add to the appearance of the tixture. t

ln accomplishing these objects, I have pro vided improved details otstructure, the preferred forms ot which are illustrated in theaccompanying drawings, wherein:

Figure 1 is a central vertical section of a connection constructedaccording to my invention. Fig. l1 is an elevation of the bell forinclosing the pipe fitting. Fig. III is a perspective view of the stayplate for straightening the down sections of the ceiling pipe.

Referring more in detail to the drawings :--1 designates the downsections of a ceiling pipe which opens through a ceiling 2 in the usualmanner and terminates slightly therebelow.

Slidably mounted on the pipe 1 is a disk 3, preferably of suitablemetal, and of suticient diameter to provide an extended bearing againstthe ceiling, and having an edge fiange -ii lor contacting the ceilingand spacing the body of the plate therefrom; the bearing hub singextended below the plane of the disk to provide an extended bearingagainst the down pipe.

Threaded onto the down pipe 1 is a reduction tting 6, having abell-shaped up- Patented Nov. 24, 1914.

per portion 7, the edge of which bears against the under face ot' thedisk 3, so that when it is tightened on the down pipe, the edge orn thebell presses upwardly against the disk and serves to hold the latter inplace.

The body ot the fitting is extended downwardly fr in the upper bell andprovided, at its lower end, with a wrench head 10 by which it may betightened on the down pipe and against the stiflening disk, and openingupwardly through the wrench head and body to communication with the downpipe bore, is a bore 11 into which the hanger pipe 11 is threaded, bothof the bores being preferably tapered inwardly to provide tapered,threaded connections between the pipes and fitting.

Vihile the connection may comprise merely the disk and fitting, l preferto use an ordinary canopy 12 for inclosing the first named parts to addto the appearance of the iixture, and also serveto assist in performingthe stitiening function oii such parts.

in order to adapt the connection Yfor use with combination gas andelectrical fixtures, i provide the disk 3 with apertures 13 and thefitting 6 with apertures 14, through which the electric light wires 15may extend, and with this form of fixture I use the ordinary inclosingtube 1G for containing the electric light wires and mount the canopy 12on said tube in the usual manner.

lWhile my improvements may be used in connection with any lightingsystem, it is particularly useful in buildings having high ceilings,wherein the long hanger pipes afford considerable leverage tending` tobend the pipes and loosen the connection when the fixtures are handledor swayed, so that leaks are formed in the pipes, the pipes loosened sothat they j ar and thereby result in damage to gas mantles or electriclight filaments, either during their installation or under conditionsoi3 use.

By threading the fitting onto the down pipe 1, while the fixture isbeing installed, any irregularity in the pipe is corrected as the diskis tightened against a flat ceiling through which the down pipeprojects, and by tightening the bell against the previously placed diskthe correction is not only supplemented, but a perpendicular bearingmaintained after the original placement of the parts, on account of theadditional leverage attained by extending the point of contact with thepipe downwardly from the point of Contact with the ceiling.

In installing the fixture, the ceiling pipes are placed in the usualmanner and the disk and itting applied thereto and tightened against theceiling to straighten the pipes, and the hanger pipe threaded into thefitting.

l/Vhen the fixture is adapted for using gas and electricity,.electricwires may then be run through the disk and fitting to the lamps, and theportions of the wires extending on the outside of the fitting, as wellas the fitting and disk, inclosed by the canopy 1l.

'ft is apparent that the simplicity of the Structure notV only does notmaterially increase the cost of the fixture, but also enables the sameto be applied without material increase in labor, as all of the partsmay be installedv by a single workman.

Having thus described my invention, what I claim as new therein, anddesire to secure byv Letters-Patent, is

l. In lighting fixtures, a stiifening disk adapted for application to aceiling pipe and having an edge flange projecting trom one of its faces,and a iitting having a threaded aperture for receiving the ceiling pipeand a bell spacedv from the aperture of the disk. y

2. In a lighting ixt'ure, a tting comprising a bell-shaped upper portionhaving a boss rising from its base into the bell-shaped portion, andhaving threaded sockets extending inwardly through said boss and fromthe end opposite the boss and meeting to form a conduit.

3. In lighting fixtures, a stifening disk adapted for mounting on aceiling pipe, and a bell having a threaded apertureand an annular baseflange of less diameter than and adapted for contacting the stifieningmember.

4. The combination with ceiling and hanger pipes, of a disk mounted onthe ceiling pipe and having an upturned edge flange and down-turnedhead, and a fitting having a central channel into which the pipes arethreaded, and having a bell-shaped upper portion bearing against theunder face of the disk adjacent the periphery thereof;

5. T he combination with ceiling and hanger pipes having suitableconnection, of an apertured disk mounted on the ceiling pipe and havingan upturned edge flange and a down-turned head, a fitting havingthreaded connection with the pipes and bearing against the under face ofthe disk, wires extended through said apertures, and a cano-py inclcsingthe disk and bell and the lower portions of said wires.

In testimony whereof I aiix my signature in presence of two witnesses.l
